Slides are not learning stand-alones. These are simply notes used to augment lectures.

Buoyancy: This is a lecture portion (39 slides; 2 MB) on buoyancy and buoyancy calculations based on my article Archimedes, A Gold Thief, and Buoyancy. Also includes "extra stuff" on significant density related items.

Diver's Guide to Hyperbaric Chambers: This is the lecture portion (82 slides; 12.3 MB) of my course in an introduction to hyperbaric chambers. This course included a field trip to Bronson Hospital (Kalamazoo, Michigan) for a chamber dive to 165 fsw.

Dive Physiology: This is a collection of slides covering various dive physiology topics from a variety of classes (128 slides, 6.7 MB). Topics include hyper and hypothermia, PFO's, Ear Issues, Near Drowning, CO₂ Issues, Shallow water Blackout, CO, Nitrogen Narcosis, DCS, Air Embolism, and Oxygen Toxicity.

Dry Suit Diving: This is the lecture portion (229 slides; 21.7 MB) of my umich academic course in dry suit diving. The "Not Being Cold" portion is an extended version of slides furnished to me by Dick Long at DUI.

Friday Night Review: This is the review session used on the Friday night (105 slides; 4.6 MB) before the open water weekend for my basic scuba students. It is my first made power point slide set. This demonstrates the level of knowledge that was present in the recreational community (the way I was trained) before the concerted effort (beginning in the early 1980's) to remove lecture topics and in-water training time from basic training.

I Am Certified, Why Not Authorized? This introductory slide set (31 slides, 3.11 MB) is used to explain the U of Michigan Diving Authorization process to those wishing to dive on university research projects.

Oxygen Enriched Air (EANx): This is the lecture portion (248 slides; 17.7 MB) of my umich academic course for oxygen enriched air (Nitrox).

Oxygen Provider: This is lecture portion of the DAN oxygen provider course (133 slides; 14.3 MB) course with an extended lecture on diving maladies / physiology suitable for the umich academic diving community.

PFO and Clearing Ears: This is lecture comments (15 slides; 0.97 MB) on the Patent Foramen Ovale (PFO) and equalizing pressure ("clearing") of the middle ear (Includes comments on Valsalva dangers and the "wonderfulness" of the Frenzel method of equalizing middle ear pressure with the environment).

River Diving: This is the lecture portion (127 slides; 17.4 MB) of a river diving course based on the St. Clair River (one of the swiftest commercial waterways in North America) in Michigan.

What Is Science Diving?: This is a slide set (36 slides, 6.62 MB) providing an overview scientific diving at the University of Michigan. This is typically used as a guest lecture in classes at the University of Michigan.

Why I Don't Train Kids: This is the talk I gave at the 2001 Our World Underwater dive show (69 slides; 3.2 MB) on my rationale for not training anyone under the age of 18.

No Cell Phones in Class: This slide set (135 slides; 19.1 MB) was developed to justify my denial of cell phones in the chemistry classes I taught. Students were surprised to see that no wireless device sold in the US has passed a consumer safety protocol.

In class, I passed around a microwave energy detector and students realized their cell phones (allegedly turned off) and laptops were producing energies exceeding the recommended long term exposure limits for microwave radiation.
